Abstract
In a power generating system utilizing waste heat of a converter, a steam turbine is connected with a generator; the steam turbine is respectively connected with one end of a condenser and an air cooling system; the other end of the condenser and the air cooling system is connected with a de-aerator via a condensate pump; the de-aerator is in an enclosed connection with a heat storing device via a first water make-up water pump; the de-aerator is connected with a steam pocket via a second make-up water pump; the converter is connected with the steam pocket via a forced circulating pump; the steam pocket is connected with a steam separator; and the steam separator is respectively connected with the steam turbine and the de-aerator. During a converting period, steam produced by an exhaust-heat boiler is led into the heat storing device; water in the heat storing device is heated by the steam and then coagulates to water, so water enthalpy value of the heat storing device is increased; and a heat supplying process of the heat storing device is completed and saturated steam is supplied. During a non-converting period, the exhaust-heat boiler does not produce steam and saturated water in the heat storing device is depressurized and evaporated in a flash; the saturated water becomes superheated water, instantly boils and evaporates naturally; continuous steam is therefore produced; and the continuous steam is supplied to the steam turbine for use after pressure adjustment.
